Access Control Online for Sale in South Africa | DIY Geek

Access control units allow you to determine who gets in and what areas they can access. Whether you are limiting access to a lab, a server room, or anywhere else, you need to make sure that you are using the latest technology. We have an array of systems that will help you to limit access throughout your building. This includes fingerprint-based systems to ensure that there is no potential for fraud. Card and code-based systems are simply not as sophisticated as bio-metrics, which is why we’re happy to offer such technology.

The act of accessing may mean consuming, entering, or using. Permission to access a resource is called authorization.

When a credential is presented to a reader, the reader sends the credential’s information, usually a number, to a control panel, a highly reliable processor. The control panel compares the credential’s number to an access control list, grants or denies the presented request, and sends a transaction log to a database. When access is denied based on the access control list, the door remains locked. If there is a match between the credential and the access control list, the control panel operates a relay that in turn unlocks the door. The control panel also ignores a door open signal to prevent an alarm. Often the reader provides feedback, such as a flashing red LED for an access denied and a flashing green LED for an access granted.

The above description illustrates a single factor transaction. Credentials can be passed around, thus subverting the access control list. For example, Alice has access rights to the server room, but Bob does not. Alice either gives Bob her credential, or Bob takes it; he now has access to the server room. To prevent this, two-factor authentication can be used. In a two factor transaction, the presented credential and a second factor are needed for access to be granted; another factor can be a PIN, a second credential, operator intervention, or a bio-metric input.
